SPECIFICATION forming part of Letters Patent No. 631,029, dated August 15, 1899.

Application filed JannarylB, 1897. Serial No. 619,578. (No model.)

To all whom, it ntcoy concern:

Be it known that I, FREEBORN F. RAYMOND, 2d, a citizen of the United States, residing at Newton, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Heel Compressing Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

The invention comprises a heel-compressing machine having opening and closing dies mounted upon the under surface of a stationary head or support, and a vertically-movable pressure-head below said first-named head, and a heel-seat former mounted upon said head to be horizontally movable thereon and also the breast-section of the die carried by said movable pressure-head and horizontally movable upon it with the heel-seat former, the said pressure-head acting to move upward the heel-seat former and breast-section of the die to engage them with the die-sections carried upon the under surface of the stationary head and with said head.

In the drawings, Figure 1 is a view in front elevation of a machine having the features of my invention. Fig. 2 is a view in vertical central section upon the dotted line 2 2 of Fi 1. tio n, illustrating the position of the various parts of the die at the end of their compressing action. Fig. 4 is a vertical section of the same parts, representing the position of the heel-seat former and breast-section of the die immediately after the compression of the heel-blank. Fig. 5 is a view, principally in inverted plan, of the side dies and the crosshead from the under surface of which they are suspended. Fig. 6 is a view in horizontal section taken upon a line immediately above the heel-seat former and in plan below said line.

A is the base of the machine. From it extend upward rods a, preferably two on each side, and which are firmly united at their lower ends to the base and carry or support at their upper ends the stationary head B. To the under surface of the stationary head Fig. 3 is a detail view, in vertical secthere is secured by cap-plates 0 slides C O, carrying die-sections D D, detachably secured to the slides. The slides have a closing and opening movement imparted to them by means of the links 0 0 respectively, the inner ends of which are pivoted to the outer ends of the slides, and the outer ends of which at c 0 respectively, are pivoted to ears or brackets c 0 extending from the sides of the vertically-movable pressure-head E. Each slide may be connected with the said ear or bracket by one or by two links. The upward movement of the pressure-head E moves upward the brackets or ears and causes the links to be straightened, thereby moving the slides O C inward and closing the die-sections D D. A downward movement of the pressure-head causes the links to be moved in a reverse direction and the slides to be moved apart, thereby separating the die-sections D D. The pressure-head E is mounted upon the said rods a and is vertically movable by an eccentric upon the main shaft e and the eccentric-strap and connection e with the pressure-head. (See Fig. 2.) The upper part of the movable pressure-head E has horizontal guideways 6 in which a plate or block F is movable horizontally from a position at the front of the machine (see Fig. 2) to a po sition beneath the die-sections D D, where it is held stationary upon the pressure-head while the pressure-head is moved vertically to present it to the upper stationary head and to the die-sections D D.

r The block or plate F is represented as moved horizontally on the pressure-head by the cam f on the cam-disk f, fastened to the main shaft, the cam being connected with the block or plate by the lever f pivoted at f to the pressurehead E and having a short arm connected with the upper end of the slide J, the slide having at its lower end a camroll f which bears upon the cam. The long arm of the lever f is connected to the sliding block or plate F by means of a link The sliding block or plate carries the heel-seat former G, which is detachable from the plate, and it also has the breast-section H of the die, which has upon its outer face the inclined surface h, which inclined surface comes in contact with the inclined surface It on the inner side of a downward projection 71 from the stationary head B. These inclines serve to close the breast-section of the die toward and upon the forward ends of the side sections of the die as the breast-section is moved upward, and the breast-section is of such height that at the end of its upward movement it laps or extends by the plate against which the bottom or tread end of the heel is compressed. (See Fig. 3.) The formerGis supported upon the section f of the said block F, the said section being large enough to hold the largest size of former which may be used. The former is represented as attached to this section by a pin which enters a hole therein, and is also represented as provided with a plane or straight front surface which abuts or bears against the inner surface of the breastblock H.

The heel-blank is represented as held upon the surface of the former G with its breast in contact with the inner face of the breast-block H by a holder M. This holder has a rounded or V-shaped surface to bear against the back of the heel-blank, and it has an outward yielding movementin respect to the inner face of the breast-block and also a downward movement, and it is also adjustable vertically. These features are provided in order that it may automatically adjust itself to heels of all sizes, and therefore hold upon the former heels of all sizes, and in order that it maybe held stationary by the contact of its upper end with the side dies while the former is being moved upwardly, (see Fig. 3,) and also in order that its height maybe varied in respect to the upper surface of the heel-seat former. I have therefore shown the holder at the upper end of a vertical arm m, which is pivoted at its lower end 192 to the outer end of a horizontal arm m and this horizontal arm is in turn pivoted at its inner end wa to the under side of the block or plate F. A spring 111* acts against the arm m to lift it and hold it in its highest position, and a spring m acts against the arm m to move the holder M toward the inner face of the breast-block and to hold it in such position. An adjusting screw m, which screws into and through a threaded hole in the arm m bears against the under surface of the block F and serves as a means for vertically adjusting the holder. The relation of the arms of the holder and of the holder to the heel-seat former and breastblock when an uncompressed heel-blank is held thereby is represented in Fig. 2. The position which the arms and the holder bear to these parts at the end of the compressing action is represented in Fig. 3.

The plate or block F, it will be observed, is used in connection with the former G and the breast-section H as a heel-blank feeding or transferring device to feed the heel-blank from a position at the front of the machine backward beneath the die-sections D D and then upward between them, the said upward movement causing the die-sections to be closed or brought together and the heel-blank compressed. The backward movement of the block F, former G, and breast-section leaves the compressed heel-blank held for an instant by the side dies D D, and the forward movement of .the .block or plate F removes these parts from beneath the die, so that annnobstructed space is provided for the escape of the compressed heel from the dies by gravity upon the incline N of the lower pressure-head, from which it slides into the trough or receptacle a. (See Fig. 2.) The compressed heelblank may not readily leave the side dies D D as they are opened, as it may adhere to the under surface of the stationary pressure-head, and I have therefore represented an additional releasing device as provided by the plate 0, movable in a guideway in the under surface of the pressure-head B, above the dies D D, the under surface of this plate forming the top of the die-cavity. This plate is made movable in relation to the side dies as the pressurehead is moved downward by means of a lever o, pivoted at o, the end 0 of which engages a backward extension of the plate and the end 0 of which is connected with the movable pressure-head by the'rod 0 There is provision for lost motion between the rod 0 and the pressure-head, whereby said rod 0 is not caused to be moved until the pressurehead has been moved downward nearly the full extent of its movement. This delaysthe movement of the plate 0 until the pressurehead has very nearly reached the end of its downward movement. It is closed upon the upward movement of the pressure-head and during the latter part of said movement. This is accomplished by the contact of the eye 0 through which the rod 0 extends, with a, collar 0", adapted to slide a given distance upon said rod and acting against a spring 0 the eye coming into contact with the collar and moving upward the rod through the medium 7 of the spring 0 thus closing 01 [I10\ ing the plate 0 inward, but with a yielding stress. The outward movement of the plate from the dies D D causes, the dies to release the heel by the wiping action which takes place between them. I do not confine myself, however, to this particular means for freeing a heel-blank from the dies, and in such case the top of the die would be formed by a stationary plate attached to the under surface of the head B. A plunger actuated by a spring or by a lever connected with the moving part of the machine and movable downward from the head 13 into the die-cavity may be used for releasing the compressed heel therefrom.

Having thus fully'described my invention, I claim and desire to secure by Letters Patent of the United States- 1. In a heel-compressing machine, thecombination of a pressure-head B, separable sections of dies mounted upon the undersurface thereof adapted to have closing and opening movements imparted to them, a hee1 seat former below said die-sections and means for moving said heel-seat former horizontally and vertically in relation to said separable diesections.
